+Release notes for version 8.6.5
+===============================
+
+GHC 8.6.5 is a bug-fix release, fixing a few regressions found in 8.6.4.
+
+
+Highlights
+----------
+
+The highlights, since the 8.6.5 release, are:
+
+- Binary distributions once again ship with Haddock documentation including
+  syntax highlighted source of core libraries (:ghc-ticket:`16445`)
+
+- A build system issue where use of GCC with ``-flto`` broke ``configure``
+  was fixed (:ghc-ticket:`16440`)
+
+- Several packaging issues with the Windows binary distributions have been resolved.
+  (:ghc-ticket:`16408`, :ghc-ticket:`16398`, :ghc-ticket:`16516`).
+
+Known issues
+------------
+
+Note that the LLVM code generator (:ghc-flag:`-fllvm`) in GHC 8.6, as well as
+all earlier releases, are affected by :ghc-ticket:`14251`, which can result in
+miscompilation of some programs calling functions with unboxed floating-point
+arguments. While originally scheduled to be fixed for this release, the fix
+ended up being more difficult than anticipated and, given that issue is not a
+strict regression from 8.4, we decided to proceed with the release.
+
+Included libraries
+------------------
+
+The package database provided with this distribution also contains a number of
+packages other than GHC itself. See the changelogs provided with these packages
+for further change information.
